| description | Draft a commit message from staged changes. Matches the style of recent commits in the repo, emphasizes why over what, and does not run `git commit`. |
Commit Message
Generate a commit message from staged changes.
Task
- Run
git diff --staged and git log --oneline -20
- Draft a commit message matching the style of recent commits
Rules
- Focus on why, not what
- Subject line under 72 characters; add bullet-point body for multiple logical units
- If
$ARGUMENTS is provided, use it as additional context
Output
Do NOT run git commit. Write the draft to /tmp/commit-message.md as the canonical artifact — chat rendering can introduce trailing whitespace invisibly, so the file (not the chat output) is the source of truth. Verify cleanliness and copy to the clipboard:
grep -nE '[[:blank:]]+$' /tmp/commit-message.md && echo "FAIL: trailing whitespace" || pbcopy < /tmp/commit-message.md
Also show the same content in a single fenced code block for in-chat preview. Do not leave trailing whitespace on any line.
